to be absolutely bloody furious with my DC?

Came home from work at 6 to find the fridge wide open thanks to either DS1 or 2. The contents were warm, meaning it has clearly been open all day. So have just spent the last 45 mins chucking the entire contents of the fridge (maybe £60 worth at a guess).

This is a fortnight after DS2 left the freezer open all night and I had to throw everything out.

Both deny it was them, neither has apolgised or gives much of a shit. I have cried because its money I can ill afford to waste, let alone that as I don't drive it is hard work restocking the fridge in one go.
